The deprecated `ordering` setting has been removed, and catalogs now always have the ordering previously provided by the "manifest" value of this setting.

Description

Manifest ordering have as far as I can tell been proven to work, problem is with it being configurable it's not something one can really rely on in public code as you just have no way to know if your users have it on or not.

When next allowed by semver I'd propose it be turned on and remain on without the option to configure.
